Default bab selection
Build-a-Box bundles can now ship with pre-selected products for each box size, defined right in the bundle settings — no more relying on hidden URL parameters. Defaults are applied automatically across the storefront purchase flow, admin "add product," and customer portal add-ons, so shoppers can move through customization faster while still editing if they want. When you set or update defaults, you can also auto-swap existing subscriptions onto the new selection, and campaign links can be tied to the default so updates flow through without re-editing each link.
